The invention relates to the technical field of vehicle early warning, in particular to an ADAS-based vehicle rear early warning method, which comprises the steps of collecting rear peripheral data corresponding to a target vehicle in real time, and obtaining a vehicle real-time state corresponding to the target vehicle and a road speed limit dynamic state corresponding to a current road; judging whether the rear vehicle distance is smaller than a safety distance threshold based on the rear peripheral data, and determining a first early warning level; judging whether the speed difference meets a preset speed difference threshold value or not, and if yes, determining a second early warning level; inputting the real-time state of the vehicle into a pre-trained anomaly recognition model for recognition, and obtaining a corresponding third early warning level; and determining a corresponding target early warning level based on the first early warning level, the first weight data, the second early warning level, the second weight data, the third early warning level and the third weight data, determining a corresponding target early warning coping strategy, and performing execution based on the target early warning coping strategy. According to the invention, the early warning accuracy of the rear vehicle can be improved.

    本申请涉及车辆预警的技术领域,尤其是涉及一种基于ADAS的车辆后方预警方法,包括:实时采集目标车辆对应的后方周边数据,获取目标车辆对应的车辆实时状态以及当前道路对应的道路限速动态;基于后方周边数据判断后方车辆距离是否小于安全距离阈值,确定第一预警级别;判断速度差是否满足预设的速度差阈值,若满足,则确定第二预警级别;将车辆实时状态输入预先训练的异常识别模型中进行识别,获取对应的第三预警级别;基于第一预警级、第一权重数据、第二预警级别、第二权重数据、第三预警级别以及第三权重数据确定对应的目标预警级别,确定对应的目标预警应对策略,基于目标预警应对策略进行执行。本申请能够提高对于后方车辆的预警精准性。
